Nearly one month after the tall, leggy blonde's friend Lauren Conradgot engaged to William Tell, the former star of "The Hills," 28, is newly-engaged, too.

As Us exclusively reported in Feb. 2012, the couple first met on the set of MTV's reality series "The City," for which Rosenman served as an associate producer. Although the series abruptly ended in 2010, the two "kept in touch and have always had crushes on each other," a source told Us.

Another source close to Port told Us earlier this year, "She is super comfortable with him and in love." Rosenman, a New York native, is the perfect match for the West Coast resident. "She likes that he is from New York because he is such a great tour guide when they visit the city," the source added.

Port, who currently has her own fashion line, has been busy with her Whitney Eve line. She dealt with tragedy in March when her father, Jeffrey Port, passed away after battling kidney cancer. "Obviously times are hard, but I'm the kind of person who is going to rise above it," she told Us in June at her Charity Ride. "You get to hold things sacred and things can be like private and intimate," she said of her life away from cameras.
